PURPOSE:To elevate the measuring accuracy in the final drying period by erasing the value of moisture content previously calculated to calculate the moving average anew when the moisture content falls below a specified reference value with the progress of drying. CONSTITUTION:The initial moisture content Mso is measures specified times and after the counting up of the results, data of the moisture content measuring interval time Ta set on a memory 15 is read out to set the counting 16 according to the data. Consequently, a measuring command signal is outputted at an interval of the time Ta to calculate the moisture content Msn by a moving average method with a control section 14. The results are compared with a reference value Msc inputted to the memory 15 previously as data. Then, when the moisture content Msn falls below the reference value Msc as the drying time passes, the results of calculation thus far used are erased and the calculation of moving average is performed again thus removing initial error otherwise added to the water content calculated thereafter. |
